Pedicel is also applied to the stem of the infructescence. The word "pedicel" is derived from the Latin pediculus, meaning "little foot". [2] The stem or branch from the main stem of the inflorescence that holds a group of pedicels is called a peduncle. [3] A pedicel may be associated with a bract or bracts. [4]

The petiole is occasionally called a pedicel, but in entomology, that term is more correctly reserved for the second segment of the antenna; [1] [2] while in arachnology, 'pedicel' is the accepted term to define the constriction between the cephalothorax and abdomen of spiders.
